rlllie niainohjiecte of this invention are First, to provide a machine adapted to autonnitieally and economically appl)r corner sealing ets-ipe to boxes or cartons. Second., to provide in a. machine ol the class clescribed, means lor conveying the cartone or looxee through the machine;I Third, to pro viele in a machine oi the class described, ineane Vfor i'orniing the sealing' strips from rolls; oi? tape or paper ribbon. lliourthg to provide in a inai'ihine ot' the vClaes described, means for applying glue or other suitable adhesive to the. sealingn strips. Fifth, to provide in a machine oi the chaacter (leseribeel. nieans t'or aiiixing the Sealing' stripe to the corners oi the boxes or packages. liiinth, to provide in ainachine of the character described, means tor folding, appli7` ingr adheeive to and eenling the ends oi the` eti-ipa over the corners of the looxee or cartons.

Further objects, and objects relating to structural letails, will lelinitely appear ilroni the detailed description to foilou'.

' vThemeans employed to accomplish the objects of this invention consist in general, of the. combination with a carton feeding menne, of a sea-lingconveyer or-'csrrier for ceri-.ying the cartons through the machine with a step bystep increment; means for forming the sealing strips from rolls of Ashaft 3 by means of the chain 5.

tape or ribbon-like strips of paper; mea-ns for applying adhesive to the sealing strips; means for applying the sealing strips to the boxes or cartons; means for applying adhesive to the ends of the sealing strips and folding and sealing the saine; and means for delivering or discharging the boxes or cartons, the several mechanisms and operations all being provided with suitable driving or actuating means whereby their opere tions are properly timed.

The embodiment of the invention illus trated in the accompanying drawing to which reference 'is made,*will now be def scribed. z 'lik The frame l is designed as n main sup port or base for the various parts and mechanisms. The several mechanisms are driven throughl the pulley 2 on the shaft 3 dis-- posed atthe rear end of the machine.

'f The cartons or boxes are delivered to' theV machine by the feed belt 9, the rear end of which is supported by thev pulley 8 on the sha-ft 7. See Figs. I, II and V.

i Thesbaft 7 is provided with a sprocket 6 which is connected to a sprocket et on the A carton l0 is shown on the feed belt,see Fig. II- the carton being shown resting agninst the stop 14 in position for the shifter to ect thereon, the mechanism being shown in the drawings in its initial position, or at the beginning of a cycle of-its movements.

In order to' insure the delivery of the eartons in the proper .shifting position, I proi Vide the feed Vbelt 9 with guides at each. side. The forward ends oi these guides diverge forwardly to form a throat to receive the cartons. See Fig. II.

A table or support Il errang-ed in front of the pulley 8 to support the `feed belt at the proper level for the cartons be shifted therefrom onto the s iding een Voyer. The table or support ll-see Figs. I and III-is supported upon arm l projecting forwardly from the pedestal I3 on which the bearings for the shaft are mounted. The forward end of the table or support v1l is inclined downwardly-see Fig. I-.so that its belt 9 and its .cad of cartons pass easily up in the same. The'guides 11 are supported by the shouldered studs Il carried by the table Vl1--see Figs. II and VI.

The stopor abutment for the cartons I0 is provided'with n. rod-like supporting arm let carried by the upwardly projecting arm lei. at the reer of the pulley 8. The carton shifter l5 is mounted on the reciprocating shuft I6 which'is supported in suitable beer,- ings carried by the framei 17, mounted on the side of the base l. See Figs. I and II. The shifter l5 is connected by the links. 18

to the oscillating leverIQ which is mounted `on the pivot I9. 'See FigsfI end The euteare ootu'eted through ie vertically reciprocating member arranged in o. bearing o@ in the cross head 50. See XIII.

The member is provided witlran en larg ment 65 which is esliding t in the 'bearing o6. The member .65 is reoiprooated by the lever 6? pivot/ed el; 67 and 'oonneeted by the linl: S8, to one erm oi the three armed lever G9 mounted to osoillote on the Shaft carried by brackets l Within the-main bese l. fIlle lever 69 is provided with a roller lf2 traveling on the com 73 on the See Fig. XIII. A spring 74 supported by the rod on the base l is connected tothe arm 69 of the lever G9. The linlr 63 is connected to the lever 67 by the pivot S3 and has threaded engagementl with the pivot Glf on the lever 69. See Fig. XIII. 'Ene lever 67 is pivotally connected tothe reciprocating member 65 by the pivotV o.' the lever being slotted to receive the `pivotA Q the connections being clearly 25 shown in Fig. XIII referred to.
